PASSENGER
MONTH CODES

Kansas adopted staggered registration with the expiration of the 1970
plate on 12/31/70. Only passenger registrations were covered and the
spread was July 1971 through June 1972. January is not used for
passenger expirations, but rather is used as an open month in which to
process calendar-year registrations:

Mid-1974 to 1980 expirations did not show monthly expiration dates on
the plate, but rather indicated the month by means of a code letter
immediately following the county code. If the DMV ever ran out of a
particular month's coded plate, it issued a plate with a "Z" in place of
the code letter and a month sticker from 1971 through mid-1974
expirations. This letter coding was used from late 1971 through
1988 expirations. From 1981 through 1988 expirations, the month was
embossed on the plate. Since the "89" base plates, a month sticker is used.

Note from Charles Fregeau:

If the DMV ever ran out of a particular month's coded plate, it
issued a plate with a "Z" in place of the code letter and a month
sticker from 1971 through mid-1974 expirations.

Since only 76 plates were dated by year, they would have had to put a
year and month on all 74 and 75 Z plates. I'm told 76 Z plates were
actually used through 1980, but I've not seen one of these yet.
